BRICK WALL CONSTRUCTION.

T o allwkom t may concern.'

Be 1t known that I, ALBERT D. BIGLER, a

citizen of the United States, residing at Clearfield, in the county of Clearfield and State of Pennsylvania, have invented new and useful Improvements in Brick VVall Construction, of which the following is a specification. y

This invention relates to wall construction and specifically to improvements in facing brick used in such structure. f

My invention is ap licable for use in the. construction of ybuildlng walls wherein.. the- -utmost stability and longevity are deslred,

together witha pleasing and ornamental appearance, and in the construction of vaults and buildings where it is essential that the structure present no external mortar joints which may be readily attacked for the purpose of destroying the wall.

The objects. are to provide a brick which, when used in the` construction of awall, will be seated or locked by lthe binding mortar with the utmost security, which isl so formed as to protect the binding mortar from moisture and the elements, which, when placed together, form ay unitary wall orA structure presenting no external mortar seams, which will be firepro'of and which, when placed in position, present a highly 'ornamental appearance.

With the above andother objects in view, my'invention consists in certain features of structure, combination and relation, and which will be set forth morefully hereinafter.

I have illustrated one embodiment of my invention in the accompanying drawings, wherein:

Figure l is a perspective view of a brick constructed in accordance with my invention. l

Figure 2 is a side elevation of a portion of' a wall constructed with my improved brick and in accordance with the invention.

Figure 3 is a perspective view of a modi? lfied form of brick constructed in accordance with my invention'.

Figure 4 is a side elevation of a portion of awall constructed with the modified form of brick illustrated in Figure 3.

Referring to the drawings, wherein similar numerals denotel like parts throughout the several views: r Referring to Figures 1 and 2 of the drawings, I provide a brick generally designated specificati@ of Letters-Patent. Patented June 13, 1922. Application led March 3,1520. Serial No. 363,006.

as 1. This brick ma be of any general shape or form and has its front face beveled, as indicated at 2. The under side of the brick is recessed, as indicated at 3, so as to provide a flat Asurface adapted to bear upon the binding mortar 4 and which forms, in conjunction with the beveled front face, a flange 5 which, in a wall construction, is adapted to overhang the front face ofthe 'next lower brick, thereby making a tight joint,'enclosin'g the mortar .from the atmosphere, and providing, in addition to the horizontal bindin surface 3 a concave and relatively vertica binding surface 6.

Referring to Figures 3 and 4 of the drawing which illustrate what nowconsider to be the preferred embodiment of my invention, 7 designates a brick which'may be provided with a central longitudinal channel, as indicatedat 8. The .front face of the brick is beveled, as at 9, and has a cut-away portion 10 adjacent the top thereof. The bottom of this modifiedform of'brick is recessed so as to provide a relatively flat binding vsurface 11 anda flangedportion 12,

which flanged portion has an inner beveledl facejas at 13, s o formed as to cooperate with the vbeveled top portion of the next lower brick in order to .form a tight joint.

The improved block in its two formsl transversely -increases in thickness from the upper portion downwardly and outwardly towards the front thereof, the rear side of each a block being vertically straight.' The front face of eachblock is also downwardly and outwardly inclinedto the lower edge oftheV projection. This increase in transverse thickness towards 'the-bottom of theblock gives the latter a stable setting and materially aids in holding the lower depend- A ing front projection of each block -firmly applied when introduced into or.made 'a component of a wall structure. There is no cement or mortar introduced between the projection and' the portion of the blockbelow which it engages andf overhangs either in the first or second form of the block, the

' interposed cement `or mortar all being confined in the recessin rear of the projection to effect a more positive lsetting of leach block and a more expeditious front finish. Moreover, all 'joints between the blocks are concealed, and the overlap of ythe projections without a cement or'm'ortar binding between the same and the adjacent portion' of the lower block will obviate water or moisture passing upwardly or seeping through the mortar or cement binding in the rear of each projection. The downward and outward inclination ot' the front face of each block provides for the formation of a wall j which will advantageously shed Water and prevent lodgment of moisture at the joints which are shielded or fully covered.

llaving Vdescribed my invention,. what I claim is:

1. A building block having a depending projection at its outer lower side portion extending the full length ot' the block and constituting the lower front terminal of the same, the block being provided with a bottom recessfrom the rear side of the block to and continuing into the rear side of the projection, the wall of the said bottom recess being straight and continuing into the rear side of the projection by a curved wall to permit the projection to fit over the upper portion of a corresponding block and provide a reduced extent of space between the bottom and top portions of adjacent blocks, the space in the bottom of the block providing for a filling of rementitious material fully over the bottom oi the block to the rear side of the projection, the block graduall y increasing in transverse thickness from the upper portion towards the bottom thereof and the front face of the block having a straight slope downwardly and outwardly from the upper portion fully through the projection.

2. A building block having a rear vertically straight side, a flat top, a front lower depending projection constituting the lower front terminal of the block, and an upper downwardly beveled corner portion at the front, the front side of the block being smooth and sloping downwardly and outwardly from the lower terminal of the upper bevel to the lower terminal of the projec tion, a recess being formed in the bottom of the block from the rear straight side of the block to and continuing into a beveled rear side ol" the projection, the beveled rear side of the projection being adapted to snugly fit over the upper bevell of an adjacent similar block and thespace providing means for a filling of eementitious material. between the bottom and upper sides of adjacent blocks.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
